to the ORG. Great to have ya. I would have him get it checked out first. That way you know for sure. Other than that, if an Oasis checks out, and the body looks straight, that is not a bad price. I would maybe start at 15.5 just to see what he will do, and go from there.
Once you get one, in this order, gauges, intake, exhaust, then a flip chip like TS or DP or something. That is the best way to do it IMO. Once again, great to have ya.
